I'd like to calculate the likeliness of an electron jumping a gap of 100 to 200 nm. I have a source emitting electrons, the potential is 10 - 20 V. What is the proper way of calculate this?(adsbygoogle = window.adsbygoogle || []).push({});

[itex]\displaystyle N = N_0 e ^{-???}[/itex] where [itex]N_0[/itex] is the amount of emitted electrons. If I use this way, how do I determine the speed of the decline, in other words the exponent in the forumla?
